01 / Duplex & Triplex Basics
What Is a Duplex or Triplex Mortgage?
A duplex mortgage finances a property containing two dwelling units. A triplex mortgage finances a property containing three units.
These properties may be purpose-built or converted from an existing home. In Quebec, they are also commonly described as plex properties.
The units may be side-by-side, stacked or arranged in another legal configuration.
Three separate dwellings may create additional rental income and different financing requirements.
Living in one unit can change the applicable mortgage-insurance and minimum-equity program.
The lender may need confirmation of unit configuration, use, permits and municipal status.
Vacancy, maintenance, property taxes, insurance and mortgage debt must still be paid.
02 / Start With Occupancy
Owner-Occupied vs Fully Rented Duplex or Triplex
This is often the first question a lender needs answered. It affects which mortgage-insurance programs and rental-income qualification rules may apply.
Live in One Unit, Rent the Others
The property may qualify under an owner-occupied multi-unit mortgage program.
You intend to occupy one of the homes as your own residence.
Rent from the other unit or units may help mortgage qualification under the relevant methodology.
CMHC's qualifying duplex and triplex programs have different LTV limits.
Budget for the whole property's mortgage, taxes, insurance and maintenance—not only the unit you occupy.
Rent Out Every Unit
A non-owner-occupied purchase is assessed as an income-producing residential property.
You do not intend to occupy a dwelling unit yourself.
CMHC's small-rental insurance program allows up to 80% LTV on eligible two- to four-unit properties.
Leases, market-rent evidence and operating expenses may support underwriting.
Existing rental properties, debts and liquidity may influence qualification.
03 / Down Payment Rules
How Much Down Payment Do You Need for a Duplex or Triplex in Canada?
Under current CMHC purchase programs, occupancy, unit count and property value matter. The table shows program-specific minimum equity frameworks, not a promise of approval.
| Property Scenario | Maximum CMHC LTV | General Minimum Equity Framework |
|---|---|---|
| Owner-occupied duplex | Up to 95% | 5% on the first $500,000 plus 10% above $500,000, subject to the program's purchase limit and qualifications. |
| Owner-occupied triplex | Up to 90% | At least 10% equity for qualifying three- to four-unit owner-occupied property. |
| Non-owner-occupied duplex or triplex | Up to 80% | At least 20% equity under the eligible CMHC Income Property program. |
CMHC Purchase generally requires an eligible owner-occupied property to be priced below $1.5 million. CMHC Income Property for non-owner-occupied two- to four-unit purchases has a separate maximum lending-value or purchase-price limit below $1 million. Other financing may have different terms.
04 / Rental Income Qualification
Can Rental Income Help You Qualify for a Duplex or Triplex?
Yes. Lenders may use qualifying rental income to support an application, but the rules depend on unit count, occupancy, insurer, lender and whether the property is the subject of the application.
The rent a lender accepts for underwriting is not the same as your actual rental cash flow.
CMHC permits an approach using up to 100% of gross eligible rent for the subject two-unit owner-occupied property.
For an applicable subject three-unit property, CMHC permits up to 50% of gross rent or a net-rental-income approach.
Under the applicable CMHC method, up to 50% of gross rent or qualifying net rental income may be used.
Current tenancy agreements and rent records help document real income.
Market-rent support or an appraisal may be required for projected income.
Rental-income calculation can differ for properties already in your portfolio.
05 / Interactive Multi-Unit Calculator
Estimate Duplex or Triplex Down Payment, Mortgage and Rental Cash Flow
Choose how the property will be used, then enter price, down payment and rent. The calculator shows a general CMHC program equity benchmark alongside a separate monthly property cash-flow estimate.
The example figures are not current lender quotes or market-rent estimates. Insurance premiums, financing fees, income tax, transfer taxes and major unexpected repairs are excluded. Owner-occupied cash flow represents rent offsetting the cost of the entire property, not personal disposable income.
Rents after vacancy, selected property operating expenses and mortgage principal and interest.
The minimum equity result is a simplified program reference based on the entered purchase price, assuming that CMHC's purchase limits and all other eligibility criteria are met. This tool does not calculate lender-accepted rental income, debt-service ratios, insurance premiums, tax liability or mortgage approval.
06 / Property Due Diligence
What Do Lenders Review About the Duplex or Triplex Itself?
A lender may need more information than a standard listing provides, especially where an older house has been converted into separate rental units.
How many dwellings exist and whether the configuration matches valuation and legal records.
Zoning, occupancy permissions, historical conversions and relevant building approvals.
Leases, rent rolls, payment history and lender-accepted market rents.
Roofing, heating, electrical, plumbing, fire separation, maintenance and insurability.
Accepted appraisal, location, comparables, income support and marketability.
07 / Hyperlocal Financing Considerations
Duplex and Triplex Mortgage Planning Across Canada
Municipal rules, permitted unit configurations, property condition and provincial tenancy requirements can change the risk and financing of a multi-unit building.

08 / Getting Mortgage-Ready
How Do You Qualify for a Duplex or Triplex Mortgage?
Borrower income, qualifying rent, existing debt, equity and lender acceptance of the property all need to work together.
Determine whether the purchase is owner-occupied or non-owner-occupied, and whether it contains two or three recognized units.
Employment or business income, credit, existing loans and other real estate obligations.
Existing leases, current rents or acceptable market-rent estimates.
Value, permitted use, condition, appraisal, insurance and marketability.
Applicable insured or uninsured stress-test rules may require qualification at a rate above the mortgage contract rate.
Consider total payments, term, amortization, penalties, prepayments and refinancing flexibility.
09 / Documentation Checklist
What Documents Should You Prepare for Multi-Unit Mortgage Financing?
Documentation may be more involved where the property already has tenants or has a less conventional unit layout.
Income and Employment
Pay information, employment confirmation, tax records or self-employed income documents where applicable.
Down Payment and Existing Debt
Proof of funds, current liabilities and financial records for other properties where required.
Purchase and Unit Details
Purchase agreement, listing, tax information, floor plans and relevant permit records.
Leases and Rent Roll
Rental agreements, current rent amounts, occupancy and market-rent evidence.
Taxes, Insurance and Utilities
Relevant operating expenses and information about how costs are divided among units.
Valuation and Property Reports
Appraisals, inspections or other lender-required assessments of the building.
10 / Financing Scenarios
Common Reasons Canadians Finance a Duplex or Triplex
The financing structure should reflect your intended use, existing properties and longer-term plan—not just the advertised mortgage rate.
First Home With Rental Income
Live in one unit and use income from other units to help cover housing costs. Qualification still depends on the applicable rental-income calculation and borrower finances.
Buy a Fully Rented Property
Compare qualifying equity, rent documentation, property expenses, vacancy and overall debt obligations.

Construction Mortgage Guide11 / Avoid Financing Surprises
What Should You Check Before Making an Offer?
A multi-unit property can look attractive on paper while the lender's valuation, accepted rental income or unit-status review produces a different result.
Unverified Unit Count
A listing describing three units is not necessarily proof that all three are lawfully recognized for the intended use.
Overestimated Rental Income
Seller-projected rents may differ from existing leases, market rents and lender-accepted income.
Underbudgeted Maintenance
Several units can mean additional appliances, plumbing, heating, tenant turnover and repair costs.
Insurance Problems
Multi-unit or converted properties can have different insurance needs and acceptance requirements.
Qualification Assumptions
Do not assume every dollar of rent will qualify or that the minimum equity framework guarantees approval.
Missing Closing Funds
Transfer taxes, inspections, legal fees, mortgage insurance and immediate repairs may require additional cash.
12 / Practical Mortgage Process
A Better Way to Prepare Your Duplex or Triplex Mortgage File
Before committing to a multi-unit property, compare the financing requirements with the property's rental income and operating costs.
Owner-occupied duplex, owner-occupied triplex or fully rented property.
Review the down payment, mortgage payment, taxes, insurance, rent and vacancy allowance.
Confirm unit status, condition, existing tenants, market rents and the lender-accepted value.
Organize documents and understand lender eligibility, terms and final approval requirements.
